    "I heated the hollowed out stud with a propane torch"

    That's part of the problem. Propane and even the "new" MAPP gas are pretty wimpy.
    Back when the busted piece was still a solid stub, several oxyacetylene heat cycles would likely have likely have gotten it right out.

    I'd ditch the WD-40 or PB Blaster, and get some Kroil, let it soak overnight...
    ...should come right out...
